lMPROVEMENTlN FORCE-PUM PS.

Specification forming part of Letters Patent No. 217,357, dated July 8,1879; application filed May 10, 1879.

To all whom it may concern:

Be it known that I, J AMES J. FINNEY, of Lampasas city, in the county ofLampasas and State of Texas, have invented certain new and usefulImprovements in the Art of Raising Water by Means of a Double-ActingS'ubmerged Force-Pump; and 1 do hereby declare that the following is afull, clear, and exact description of the construction and operation ofthe same, reference being bad to the annexed drawings, making a part ofthis specification, and to the letters and figures of referenee markedthereon.

Figure 1 of the drawings is a representation of a side elevation, partlyin section; and Fig. 2 is a sectional detail view.

My invention relates to that class of force pumps which are to besubmerged and are double-acting; and it consists in the construction andarrangements of the parts, as the same will more fully herein appear.

A are the cylinders of the pump, connected by the ties at. B is thewatercbamber, constructed spherical and formed of two hemispheres, b I),provided with flanges b and packing b, and they are attached by means ofthe bolts b and rings b b 0 are curved coneshaped pipes, connecting thecylinders of the pump with the water-chamber. The large ends of thesepipes are equal in diameter with the cylinders, and the other ends enterthe bottom of the water-chamber B. The check-valve of each of thesepipes O is located at the end of each of them, which is flush with theinside of the chamber; and it consists in a metallic ball or sphere, c,and so constructed and arranged, in connection with the concave bottomof the chamber, that unless operated upon by some force they will closethe pipes.

D is a discharge-pipe, extending from the spherical or dome-shaped upperpart of the water-chamber.

The standard E for the walking-beam of the pump is attached to andsupported by the ties a.

The walking-beam F is operated by power, and actnates the two plnngers ff. These plungers are provided with rubber spheres f, serving as valves,retained in position by the baskets f 'f, which are secured to the bulbb of the plunger, and the packing f being interposed between the basketsand bulbs, and

retained in position by the bolts that retain the baskets. There is alsoa basket, f located in the Water-chamber, extending downward over theopening of the discharge-pipe D, to prevent the ball-valves from beingforced into the discharge-pipe by the ontflowin g water- I am aware thatsubmerged pumps are not broadly new, and I do not broadly claim them.

What I claim is- In a submerged double-acting force-pump, the twocylinders A, united by the ties ayin combination with the two curvedpipes Oand the water-chamber B, formed of two hemispheres and providedwith two ball-valves, the plungers f f provided with the ball-valves f,basket f 1 f and packing f formed, constructed, and operating as and forthe purposes substantially as set forth.

' In testimony that I claim the above I have hereunto subscribed my namein the presence of two witnesses.

JAMES J. FINNEY.
